Specification of Letters Patent.

Patented July 22, 1919.

Application filed February 1, 1918. Serial No. 214,837.

T 0 all whom, it may concern:

Be it known that I, JAMEs LEVER RUSH- TON; a subject of the King of Great Britain, residing at Kay Street Works, Bolton, in the county of Lancaster, England have invented new and useful Improvements in Machines for Opening, Scutching, and Similarly Treating Cotton and other Fibrous Materials, of which the following is a specification.

My invention relates to improvements in machines for opening, scutching and similarly treating cotton and other fibrous materials, and particularly to that class of machine in which the opening and cleaning of the fibers is effected by a porcupine cylinder or a bladed beater in a cylindrical casing composed wholly or partly of cleaning or beater bars.

In one arrangement it has been proposed to construct the cylindrical casing with cleaning bars extending around the whole of the casing; but the more customary and almost universal practice is to employ a set of beater bars for a length of about one third to one-quarter of the circumference of the cylindrical casing and to follow these beater bars with a set of either cross bars or longitudinal bars forming in part a short section of the cylindrical casing and for the remainder the bottom of the passage leading to the cages.

According to my present invention I dispense entirely with the subsidiary cross bars or longitudinal bars and I construct rather more than the lower half of the cylindrical casing of beater bars only the said bars ex tending from a point about five or six bars above the horizontal axial plane of the cylinder or beater and below the feed rollers to a similar point on the opposite side of the casing whence the fibers are delivered into a passage and pass downward directly to the dust cages.

I illustrate my invention on the accompanying four sheets of drawings in which Figure 1, is a sectional elevation of an opener, scutcher or like machine showing my improved construction of the casing as applied to a porcupine cylinder and Fig. 3, is a similar view showing the application to a bladed beater.

Figs. 2 and 4 are similar views to Figs. 1

and 3 respectively but showing an alternative construction of the passage leading from the beater to the dust cages.

Similar letters refer to similar parts throughout the several views.

Referring first to Fig. 1, a designates the porcupine cylinder; at its shaft; 6 the upper casing; c the usual adjustable stripping rail; 0?, cl, d d (i a known arrangement of five driven feed rollers; 6 one of the weighted pedal levers of the feed regulating mechanism; 7 the traveling feed lattice; g, g the dust cages; h the fan; and i the dead chamber for the reception of dirt and solid impurities removed from the cotton or other fibrous material by the action of the beater in the usual way. All the foregoing parts are of the ordinary known constructions (except that the dead chamber 2' is of rather greater capacity than usual) and operate in the known manner.

According to my invention as already stated I construct rather more than the lower half of the cylindrical casing of beater bars j only, the bars j extending say from just below the feed inlet which is between the roller cl and the pedal lever e to the sheet metal part on which forms the entrance or mouth and one side of the passage 70 whence the fibers from the beater cylinder are delivered and pass downward directly to the dust cages .g, g.

In Fig. 2 the arrangement is identical with that shown and described with reference to Fig. 1, except that the passage 73 leading from the beater to the cages g, g is of different form.

In Figs. 3 and 4 the constructions correspond with Figs. 1 and 2 respectively except that the porcup-ine cylinder a is replaced by a bladed beater a and that another lmown arrangement of three driven feed rollers cl, cl, d is shown instead of a nest of five as in Figs. 1 and 2. Owing to the increased cleaning surface available in each of the constructions illustrated the fibers are far more effectually cleaned than ,in the usual construction above indicated and all air currents are obviated except those set up by the porcupine cylinder a or bladed beater n and by the action of the ordinary fan h which draws the fibers to the dust cages.

and an outlet of approximately 8 form through which the fibers delivered from the beating elements pass first upward and then downward to the cages.

In testimony whereof I have signed my name to this specification.

JAMES LEVER RUSHTON.

What I claim as my invention and desire to secure by Letters Patent is A machine oi? the class described c0n1prising a rotating beating element, a casing hav- 5 ing an inlet and outlet disposed above the axis of said element, and beater bars constituting the lower part of said casing and extending from the inlet to the outlet thereof,

copies of this patent may be obtained for five cents each, .by addressing the Commissioner of Patents,

Washington, D. 0.
